CHALLENGE 25

I had a dream today, then I woke up at 3:00 a.m. and couldn't sleep again.
It's a dream about the study session. There were very few people in the class, about seven or eight. Everyone was working on very difficult physics problems. Two people were discussing a problem...
I think I had this dream because the semester was over and the final exams were coming up next week. I was surprised to find out that my dreams usually only show up my classmates from middle school or elementary school. It's true that I had a bad time in high school and college. And I'm quite jealous of students who can discuss problems with each other.
In high school, I started out in a key class, but on my first test I was in the bottom 100 of my grade, and it gave me a huge trauma. I'm not sure if I've gone out of this trauma. The person who did the most damage to my spirit was my grade 10's deskmate. She used to tell me that we were alike and that we would be very good friends. I believed it. But after that I found we are completely different! She was very, very selfish and she only wanted others to share what they had but was completely unwilling to share what she owned. The class teacher in my grade 11 was so bad-tempered that one student's mistake or even her own mistake would lead to corporal punishment for the whole class. I'm thankful for my grade 12's deskmate. She was very nice and helped me a lot, but we don't have contact now either.
In college, it was recently the end of the semester. The teacher has drawn a lot of key points of the exam that need to be sorted out. Many dormitories divide the work of organizing notes, but in my dormitory, each does our own. When I was a freshman, I tried to work together, but no one accepted. I think our relationship is just living in the same dorm.

After I woke up from the dream, I was sad to open my phone to review the points of physics friction in high school... Then it was 5:00 and I was up.
